A couple quick magnet boards I made. They are super easy. I got a (3)pack of cookie sheets from Wal-Mart for $3.89, took the middle size and glued some scrapbook paper to the back. Drilled some holes through the top and fed a ribbon through. They were fun to make and the containers will hold embellishments and pins for my crafts.
Much cheaper than buying sheet metal, and aren't as heavy duty as the cookie sheets that I use in my kitchen.
